OEE (Overall Equipment Effectiveness) is a key performance indicator measuring production effectiveness during planned production time. OOE (Overall Operations Effectiveness) includes the time that machines are stopped due to repair or inspection. It measures production effectiveness across both scheduled and unscheduled time, i.e. total operations time. TEEP (Total Effective Equipment Performance) is a measure of effectiveness based on all available time during a particular period, which includes non-shift time, e.g. one week = 7 days x 24 hours.
